Gravitational lensing often evokes images of a cosmic funhouse mirror: duplicated galaxies, dramatic arcs and distorted shapes. But the web-like, large-scale structure throughout the universe also ...
XRISM has uncovered how galaxy clusters evolve—violent mergers create turbulence, preventing hot gas from cooling. This ...
According to Einstein’s theory of general relativity, gravitational waves warp spacetime. In the process, they could imprint ...

Interesting Engineering on MSNAtomic clocks could reveal interaction between Einstein’s relativity, quantum mechanicsA new study in Physical Review Letters has used atomic clocks to study relativistic effects in interacting quantum systems.
Gravitational potential energy is the energy an object has by virtue of its position above the surface of the Earth. When an object is lifted, work is done. When work is done in raising the height ...
Any object lifted above the ground has gravitational potential energy (\(E_{p}\) or GPE). The amount of gravitational potential energy an object has on Earth depends on its: mass; height above the ...
